Question 769844
ASSIGN VARIABLES TO EVERYTHING
L=9% salt solution
H=24% salt solution
T=18% wanted salt solution
M=250 mL volume wanted salt solution, amount of solution
u= volume to use of the 9% solution
v= volume to use of the 24% salt solution


MAKE EQUATIONS


{{{(Lu+Hv)/M=T}}} and {{{u+v=M}}}



SOLVE FOR THE UNKNOWN VARIABLES, u and v
& then
SUBSTITUTE GIVEN VALUES TO FIND VALUES FOR u and v
